The feeling that 'no one is listening to me' make us want to spend time with machines that seem to care about us.

These days, when people are alone, or feel a moment of boredom, they tend to reach for a device. In a movie theater, at a stop sign, at the checkout line at a supermarket and, yes, at a memorial service, reaching for a device becomes so natural that we start to forget that there is a reason, a good reason, to sit still with our thoughts: It does honor to what we are thinking about. It does honor to ourselves.

We have relationships with many different things, creatures and beings. We have relationships with cats, with dogs, with horses, and we know that there are certain things they can't do. So we'll add robots to that list, and we'll learn what they can and cannot do. No harm, no foul.

We used to think, 'I have a feeling; I want to make a call.' Now our impulse is, 'I want to have a feeling; I need to send a text.'

Technology is seductive when what it offers meets our human vulnerabilities. And as it turns out, we are very vulnerable indeed. We are lonely but fearful of intimacy. Digital connections and the sociable robot may offer the illusion of companionship without the demands of friendship. Our networked life allows us to hide from each other, even as we are tethered to each other. We’d rather text than talk.

My own study of the networked life has left me thinking about intimacy - about being with people in person, hearing their voices and seeing their faces, trying to know their hearts. And it has left me thinking about solitude - the kind that refreshes and restores. Loneliness is failed solitude.

The kind of solitude that refreshes and restores is very important, not just for children, not just for adolescents, but for all of us. If you don't teach your children how to be alone they will only be able to be lonely.
